[R-390] Off-topic request

[Andy Jackson G8JAC]

Please forgive the off-topic request, but someone over there might know.
Can anyone point me towards finding a copy of Signal Corps Technical
Bulletin Sig E17 which deals with the WW2 Japanese Type 94-6 field radio.
This radio also gets mentioned in Technical Manual TM E11-227A. Signal
Communications Directory, Japanese Radio Communication Equipment. 1944,
although in less detail.

Any pointers greatly appreciated.  Thanks.
